The future and present of technology are in the cloud. This book was written and released at a time when people in the modern world were emerging to accept that technology played a significant role in their daily lives. This book aimed at educating readers and showcasing the numerous applications of cloud computing technology. 

Humanity has faced several challenges as a result of many social and economic concerns. One benefit of dealing with such difficult and complex difficulties is that it has once again highlighted the value and function of cutting-edge technology in improving the lives of people. With the use of cloud services, businesses may transform their IT resources into a self-service, elastic, and adaptable set of resources that they can more quickly expand and manage to meet shifting business needs. Although there are numerous different ways to supply cloud computing services, two fundamental services are necessary in order to integrate cloud computing strategically into a larger computing infrastructure. These include Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) (PaaS). IaaS refers to the services that give you on-demand access to computing and storage resources. You may create applications to support the business using PaaS, which is a set of services that sits on top of IaaS. In reality, a lot of businesses discover that the cloud supports greater collaboration between business and IT leaders, allowing them to more swiftly adapt to shifting market circumstances. The book offers case studies of a variety of contemporary compute, storage, and application cloud services to highlight the capabilities and constraints of the present cloud computing service providers. This enables the reader to comprehend the procedures required to apply cloud computing to their own unique pursuits. This, we hope, will encourage readers to tackle them in their own upcoming study and development. We think a larger audience, including systems architects, practitioners, developers, new researchers, and graduate students, will find the book useful as a reference.

We have made an effort to design a thorough book that imparts knowledge using a hands-on, immersive method, giving the reader the direction and information needed to create functional code for actual cloud applications. We believe that the simultaneous development of practical applications and traditional instructional material in the book furthers learning.
The book is comprised of 5 segments for organisational purposes. Part I Provides an overview of cloud computing, including cloud deployment models, cloud service models, and development of cloud-based applications. Part II Introduces the fundamental technologies, such as Parallel and distributes computing and their significance. Part III explains how common cloud services including compute, storage, databases, applications, analytics, networks, and deployment are categorised. Part IV introduces the underlying technologies, and deep down study of virtualization. Part V outlines approaches for authorization authentication, identity and access management, data security, data integrity encryption, and key management as well as an introduction to cloud security.
